CARDING-'MACHINE Specification of Letters Patent.

Patented May 25, 1909.

Application led February 28, 1903, Serial No. 145,542.

yTo all whom 'it may concern: 'Be it known that LVVILLIAM BARBER, a

kcitizen ofthe United States, residing in Bridgeport, rPeniisylvania,have invented certain Improvements inCardiiig-Machines, of

'which .the followingis a specification.

My invention relates to that class of carding machines or cardingengines in which the fibrous material is passed through the machineorxengine in anjuiibrolren sliver, sheet f or web, to a'pair or set ,ofrub rolls by the acjtioii of ywhich such sliver, sheet or web after ithas ybeen divided by suitable means, such as are usually provided, isformed into slubbing. y i, Y

rThe slubbing may beniade without any preliminarywashingor scouring ofthe ma- 1 terial, oran y previous combing of the sliver,

sheet or web.

The object of my invention is to straighten the 'liber andtliereby takeadvantage of the long staple of the material operated upon,

producing abetter slubbing than has been possible in carding machines ofthe general companying drawings, in which:

n Figure 1, is a view in diagram of sufficient 1 lof a carding machineto illustrate my inventiongFig. 2, is a similar view illustrating` a,modification of myk invention.; Fig. 3, is anV Yenlargedsectional viewillustrating a detail of myiiivention, and Figs. 4 and 5, are viewsillustrating,further details of my invention.

My improved cardiiig means may be eml ployed `with wools or other fibersin the grease ,if desired, or with washed and scoured stock.rv y, n`vThe object of my invention is to make a smoother,r evener .andstronger yarn than has heretofore been made, which is especiallyr.useful in the manufacture of carpets and t other fabrics in which theyarn is cut for pile effect, but which may be used to advantage for` anyrrrtextile material@ The liber being straighter, the yarn is evener andstands up better'.

- lnFig. l, 1 represents the main cylinder, @covered as usualwith theordinary card yclothing and rotated the present instance' f inthedirection of the arrow x. regular order around this cylinder are theArranged. in

workers 2 also covered with card. clothing, the teeth of which are setin the same manner as those of the main cylinder, which teeth,however,are opposed to the teeth of l the main cylinder directly opposite theformer. Adjacent to each of the workers 2 are the strippers 8, shown indetail in the enlarged view Fig. 3, which strippers are covered withtextile fabric, leather or other suitable material that will insure asmooth or comparatively smooth surface. By coinparatively smooth l meana surface that will support the sliver in a continuous unbroken web orfleece. The workers and strippers rotate in the direction indicated bythe arrows. As clearly illustrated in the drawings, the sliver, sheet orweb of the material under operation in passing around the main cylinderis alternately caught up from the main card by the workers and removed'from said workers by the strippers and passed onto the main cylinderagain. l find in practice that a smooth or comparatively smooth surfacedroller will act as a stripper to remove the fleece from the workers andpass it onto the main card.

The strippers being covered with leather or other smooth material canbeset very close to the cylinder, say U64 of an inch. When the card is inoperation the surface of the strippers readily covers with grease orother foreign matter contained Within the material under operation,causing complete contact of the grease covered stripper with thecylinders. The friction of the wire covered cylinder against the greasecovered stripper removes any excessof grease thereby keeping the contacteven and uniform. The fiber, by this close and even contact of thestrippers and cylinder, is spread all over the cylinder in an even anduniform manner, thus allowing an equal portion of the stock or fiber tobe taken by the doffing rings.

if so desired., the Wipe roller or stripper may be fluted, as shown inFig. 4, or have small holes bored into it, as shown in Fig. 5 thusfurther enhancing the stripping qualities. VIn both instances, thesurfaces will be smooth or comparatively smooth, and will have a solidbody in contradistinction to the penetrable body surface formed by thecard clothing.

The strippers 3 being coated with leather or other smooth material andpresenting a substantially smooth and solid surface to the clothing ofthe cylinder and tension rollers, allow the fibers to pass over thesurface of said strippers; not entering the same as in the case whererolls coveredD with card clothing are employed. Furthermore, I am en ivoabled to use workers much larger in diameter than usual, therebybringing a greater surface of the card clothing into contact with thestock between the cylinder and said Workers, as the stock is not carriedover the top of the workers in the manner common to the old process ofcarding.

The object of my invention is to effect a drawing and straightening ofthe fibers as the sliver, sheet or web leaves said strippers. To dothis, I arrange tension rolls 4, as shown in Fig. 1, which rolls lieover close to or in contact with the strippers 3, and being rotated inthe proper direction, effect a drawing action between said rolls and thestripers while the fibers are being taken up again by the main cylindercard, causing the fibers to lengthen out and straighten, therebyremoving from the fmished slubbing the twisted and confused appearanceusually present. By having smooth or comparatively smooth surfacedrollers for the strippers, the drawing and straightening action isenhanced and the fiber is not likely to be torn as with a roller havingtoothed clothing. The web after it passes the final worker may becarried to any suitable mechanism for dividing it into strips, whichstrips are afterward passed to the rub rolls which form them into theslubbing noted. The rolls 4 may be of j plain metal, but I prefer thatthey shall be covered with leather or other suitable material, shown at5 in Fig. 3, and they are arranged to be adjusted from and toward thestrippers so as to regulate the amount of tension and drawing effectupon the fibers of the web.

In F ig. 2, I have shown another form of apparatus for carrying thisdrawing operation into effect as the iieece is passed through thecarding machine. This consists in providing a pair of tension rolls,which I have indicated at 4, which rolls are preferably covered asindicted with reference to the rolls 4, and are arranged adjacent to thestrippers so as to receive from the same the web orsheet underoperation. In this form of my invention, the drawing will be effectedbetween the tension rolls 4a and not between one of said rolls and oneof the strippers.

The main cylinder of the carding machine is preferably speeded as underordinary circumstances and the workers are run slower and the strippersat the same speed as the workers or slightly in excess of such speed, asmay be desired. The rolls 4 and 4a, however, have a surface speed aboutthe same as the strippers.

The improved mechanism forming the subject of my invention may be usedon finisher (condenser) card, first and second breaker', separately orin connection with all of them simultaneously. It is applicable for thepreparation of the fibers of wool, cotton, silk, flax and jute, for thecombing process;

for the carding or combing of wool for worsted, worsted waste, ringWaste, shoddy, or any other material in which straightening carding orcombing is desired, or used.

Having thus described my invention, I claim and desire to secure byLetters Patent:

1. The combination of a main carding cylinder, a worker roll mountedadjacent thereto and serving to catch up the stock from the cylinder, asmooth-surfaced stripping roll for passing the stock back to thecylinder, and a rotatable smooth-surfaced roll of less diameter than thestripper adjacent to the latter and in nominal contact therewith forimparting tension to said stock as it passes betweensaid rolls onto thecylinder.

2. rIhe combination of the main carding cylinder, a worker roll adjacentthereto and serving to catch up the material from the main cylinder, asmooth surfaced stripper for passing the material from the worker backto the main cylinder, and means for imparting tension to the materiai asit passes from the stripper to the main cylinder.

3. The combination of the main carding cylinder, a worker mountedadjacent thereto and serving to catch up the material under operation, asmooth surfaced stripper in proximity to and serving to receive thematerial from the worker, and a tension roll also having a smoothsurface mounted ad j acent to the stripper for the purpose of engagingthe web as it is fed to the main cylinder again, the contact of saidroll with the stripper effecting the drawing and straightening of theliber of the material under operation as the latter is carried forward.

4. The combination of the main carding cylinder, a series of workersadjacent thereto and adapted to catch up from said main card thematerial under operation, a series of smooth surfaced strippers adjacentto said workers to remove the material and pass it again to the maincard, and tension rolls mounted in proximity to the strippers, andserving to engage the lieece as it passes from said strippers to themain card.

5. The combination of the main carding cylinder, workers adjacentthereto, smooth surfaced strippers adjacent to said workers and servingto remove therefrom the material under operation, and smooth surfacedtension rolls adjacent to the strippers and adapted to act with saidstrippers to pass the material back to the main cylinder, said tensionrolls serving to draw and straighten the fibers of the material.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.

WILLIAM BARBER.
